lthough no longer required by the fire code, most fire protection professionals require rooftop heliports have a Fuel/Water Separator to contain a deluge of spilled fuel in the event of a helicopter accident, preventing fuel from entering the building’s roof drains and ultimately, city storm sewers where a fire or explosion could occur. Yet our Fuel/Water Separator permits normal rainwater runoff from the heliport to pass through to the roof drains as it did prior to the heliport being constructed. Stainless steel for minimal maintenance. Prices starting at: $14,975. USD FOB Ex-Works New Jersey. 10 year warranty.
